[1-1.IDMA]

First, the technology related to IDMA is described now with reference to Fig. 1 to 4.Fig. 1 to 4 is the technology related to IDMA Explain diagram.

It is nonopiate many as the 5G radio access technologies after Long Term Evolution (LTE)/LTE-Advanced (LTE-A) Access and caused concern in location.

In the OFDM (OFDMA) or Single Carrier Frequency Division Multiple Access (SC-FDMA) that are used in LTE, radio resource quilt It is assigned as causing to be overlapped between their subscriber's installations not in the cell.Radio resource be for radio communication frequency or when Between resource, and there are various types of radio resources (such as, Resource Block, subframe, resource element etc.).For without friendship This radio access technologies that radio resource is distributed in the case of folded are also referred to as orthogonal multiple access access.

Fig. 1 represents the example of the radio resources allocation in orthogonal multiple access access.In Fig. 1, horizontal axis indicates frequency, And represent the radio resource for distributing to user in different colors for each user.As shown in fig. 1, for example, orthogonal many During location is accessed, user can be assigned to along the different resource block (RB) of frequency direction.

On the other hand, in non-orthogonal multiple access, radio resource is distributed by this way：Radio resource is extremely Overlapped between few part subscriber's installation in the cell.When being accessed using non-orthogonal multiple, by the subscriber's installation in cell The signal for sending and receiving can be interfering with each other in radio spatial.However, receiving side can be processed by predetermined decoding obtains every The information of individual user.In addition, known in theory：When suitable radio resources allocation is realized, non-orthogonal multiple is accessed can Realize accessing message capacity (or cell communication capacity) high than orthogonal multiple access.

Fig. 2 represents the example of the radio resources allocation in non-orthogonal multiple access.In fig. 2, horizontal axis indicates frequency Rate, and represent the radio resource for distributing to user in different colors for each user.As shown in Figure 2, for example, in anon-normal In handing over multiple access to access, the Resource Block (RB) overlapped along frequency direction can be assigned to user.

IDMA is classified as an example of the radio access technologies of non-orthogonal multiple access.In IDMA, it is used for Device in sending side is interleaved to sending signal so that the intertexture pattern of identifying user signal is allocated differently to each User.Then, the device in receiving side use respectively it is corresponding with the intertexture pattern for distributing to each user deinterleave pattern to Family signal is decoded.IDMA has the advantages that the low signal treatment load on the device of sending side.Especially filled from user In the standby up-link (UL) for arriving eNB, this advantage is considered as critically important.

Fig. 3 represents the example of the basic structure of the dispatching station 10 that radio communication is performed using IDMA.As shown in Figure 3, send out See off 10 include error correcting code circuitry 11, interleaver (π i) 12, digital modulation circuit 13 and radio frequency (RF) circuit 14.Error Correction of Coding Circuit 11 carries out wrong forced coding to the information bit string of user i.Interleaver (π i) 12 is to perform the friendship for user i to it Knit the interleaver of setting, and information bit string to Error Correction of Coding is interleaved.Digital modulation circuit 13 is modulated in a digital manner The information bit string of intertexture.The signal that 14 pairs, RF circuits are modulated in a digital manner performs various signal transactings, and is sent through antenna Wireless signal.Intertexture setting is and the related setting of at least one of intertexture pattern or weaving length (Interleaver size).

Fig. 4 represents the example of the basic structure of the receiving station 20 that radio communication is performed using IDMA.As shown in Figure 4, connect Receiving station 20 includes RF circuits 21, demultiplexing circuit 22 and decoding circuit 23.21 pairs of wireless communications received by antenna of RF circuits Number various signal transactings are performed, and by signal output to demultiplexing circuit 22.Demultiplexing circuit 22 has will be by closing The composite signal obtained into the signal from user is separated into the function of the signal for each user, and the user that will be separate Signal output gives correspondence decoding circuit 23.For example, decoding circuit 23i includes performing it setting that deinterleaves for user i Deinterleaver (π i^-1) 24, error correction decoding circuit 25 and performed to it interleaver (π i) set for the intertexture of user i 26.Decoding circuit 23i receives the subscriber signal from user i, and by deinterleaver (π i^-1) 24 perform deinterleave treatment simultaneously And by the perform decoding of error correction decoding circuit 25.When subscriber signal has been correctly decoded, decoding circuit 23i output user's letters Number as user i information bit string.In addition, decoding circuit 23i is interleaved by 26 pairs of decoded signals of interleaver (π i), and The signal is returned into demultiplexing circuit 22 as the subscriber signal for user i.Performed for all subscriber signals this Subscriber signal is returned.Demultiplexing circuit 22 separates the subscriber signal of return again, and the subscriber signal that will be separate is again defeated Go out to decoding circuit 23.Receiving station 20 repeats the signal transacting come right by demultiplexing circuit 22 and decoding circuit 23 Subscriber signal is decoded.

[1-2. wireless communication systems]

(1-2-1. general structures)

Fig. 5 is the explanation diagram of the general introduction of wireless communication system in accordance with an embodiment of the present disclosure.As shown in Figure 5, root Wireless communication system 1 according to the present embodiment includes dispatching station 100, receiving station 200, communication control unit 300 and core network 500。

Dispatching station 100 is the device that data are sent to receiving station 200.For example, dispatching station 100 is the evolution in cellular system Node B (eNB) or access point.In addition, receiving station 200 is the radio communication device for receiving the data sent from dispatching station 10.Example Such as, receiving station 200 is the subscriber's installation (UE) in cellular system.

Figure 5 illustrates example in, dispatching station 100A is to one or more terminal installations inside cell 400 The eNB of radio communication service is provided.In addition, receiving station 200A and 200B are the UE that radio communication service is provided by eNB.For example, ENB 100A can send data to UE 200A and 200B.ENB 100A are connected to core network 500.Core network 500 is through gateway Device is connected to packet data network (PDN).Cell 400 can according to any wireless communication system (such as, Long Term Evolution (LTE), LTE-Advanced (LTE-A), GSM (registration mark), UMTS, W-CDMA, CDMA 2000, WiMAX, WiMAX 2 or IEEE 802.16) operate.

Here, a device can be used as dispatching station 100 or receiving station 200.In addition, a device can both be used as dispatching station 100 are used as receiving station 200 again.For example, UE can be used as being received from eNB by downlink the receiving station 200 of data, and also use Make the dispatching station 100 to eNB transmission data by up-link.In addition, eNB can be used as receiving data from UE by up-link Receiving station 200, and also serve as by downlink to UE send data dispatching station 100.

In addition, UE can each other perform radio communication.Figure 5 illustrates example in, UE 100B directly hold with UE 200C Row radio communication.This communication system is also referred to as device and device (D2D) is communicated.D2D communications can be identified as except honeycomb system The communication outside the communication between eNB and UE in system.In addition, the centralization powerful not as the eNB in cellular system Communication in the wireless communication system of control node can be included in D2D communications in a broad sense.For example, WLAN (WLAN) system can be the example of this wireless communication system.

Communication control unit 300 is with the device of the radio communication in cooperation mode control wireless communication system 1.In Fig. 5 In in the example that shows, communication control unit 300 is server.For example, communication control unit 300 controls dispatching station 100 and connects Receive the radio communication in station 200.In addition to the example shown in Fig. 5, communication control unit can for example be implemented as dispatching station 100th, internal or external any device (physical unit or logic device) of receiving station 200 or core network 500.

The operation related to the radio communication in the wireless communication system 1 according to the present embodiment will be described.

First, the treatment when radio communication is performed from eNB to UE will be described.

In normal cellular system, eNB is in many cases with concentration in downlink and uplink wireless communications Mode manages/control radio resource.In case of a downlink, first, eNB notifies radio resource to UE, will be by The down-link data channel (for example, PDSCH) of reception is already allocated to the radio resource.For this notice, generally Use control channel (for example, PDCCH).Then, eNB is using distributing to the downlink radio resource of each UE to each UE Send data.

UE attempts receiving the signal for sending using the radio resource of the down-link data channel notified by eNB, and Signal to sending is decoded.When UE is successfully decoded to signal, UE sends ack signal to eNB, and works as UE When cannot be decoded to signal, UE sends NACK signal to eNB.For example, the cyclic redundancy of the data by being added to transmission Result of verification (CRC) verification etc., it may be determined that the success or failure of decoding.

When receiving NACK signal or not receiving return signal from UE, eNB determines that data is activation has failed.Then, ENB is performed and is resend treatment for resending the data that its transmission has failed.In treatment is resend, as above-mentioned place It is the same in reason, perform the notice of the radio resource for being allocated down-link data channel from eNB to UE and use notice Radio resource data is activation.ENB resends treatment, until receiving ack signal from UE or reaching again The predetermined maximum times for sending.

(1-2-3. uplink scenarios)

Next, the treatment when radio communication is performed from UE to eNB will be described.

Different from downlink, in the uplink case, the notice and UE that eNB performs radio resource perform data Send, and in the downlink case, eNB had not only performed the notice of radio resource but also had performed the transmission of data.Specifically, ENB notifies to be allocated the radio resource of the uplink data channel (for example, PUSCH) that will be used for sending to UE. Control channel (for example, PDCCH) is generally used for the notice.Then, UE is sent out using the uplink data channel for notifying to eNB Send data.

Treatment is resend similar to downlink scenario.For example, being returned when receiving NACK signal or not receiving from eNB During letter in reply, UE determines that data is activation has failed and performed and resends.Here, eNB can be with the transmission of NACK signal simultaneously Execution will be used for the notice of the radio resource that UE resends, because eNB controls and management uplink data channel Radio resource.

(1-2-4.D2D signal intelligences)

Finally, the treatment in the D2D communications for performed between UE radio communication will be described.

UE in sending side can send data in the case where the radio resource for transmission is not notified.For example, passing through Notice from external device (ED) or by performing carrier sense, spectrum-sensing etc., UE in sending side is recognizable will to be used for The radio resource of transmission.Resend treatment identical with above-mentioned downlink scenario and uplink scenario.

Figure 10 is the example of the logical construction of the wireless communication unit 110 for representing the dispatching station 100 according to the present embodiment Block diagram.Figure 10 represents the example of the structure of a part for wireless communication unit 110, wherein being performed and being sent by dispatching station 100 The interleaving treatment of the transmission block (TB) of the corresponding bit sequence of target.Although Figure 10 shows turbo yards is considered as forward error correction (FEC) Example topology example, but in addition to turbo yards, it is possible to use other FEC codes, such as convolutional code and low-density parity are examined Test (LDPC) code.As shown in Figure 10, wireless communication unit 110 includes that CRC adding devices 111, CB cutting units 112, CRC add Plus unit 113, FEC coding units 114, de-rate matching unit 115, CB connection units 116, interleaver setting unit 117 and CW Interleaver 118.

First, CRC is added to TB by CRC adding devices 111.Then, CB cutting units 112 are according to turbo yards of code length The sequences segmentation of CRC bit into one or more error correcting code sequences code block (CB) will have been added.Can be by the quantity (C) with CB equally Many parallel processings perform the treatment of the CB of segmentation.Used as the treatment for each CB, be added to for CRC by CRC adding devices 113 Each CB, FEC coding unit 114 performs FEC codings (for example, turbo is encoded), and de-rate matching unit 115 performs speed Match to adjust encoding rate.Thereafter, CB connection units 116 connect the CB from the output of de-rate matching unit 115 to produce single position Sequence.Institute's bit sequence is considered as code word (CW).The CW corresponds to TB after coding.Interleaver setting unit 117 The intertexture for performing CW interleavers 118 according to |input paramete is set.In addition, controller 130 will for example use control channel from by eNB etc. The information that the control information of notice is obtained is input to interleaver setting unit 117 as parameter.Then, CW interleavers 118 are performed The interleaving treatment of the CW produced by connecting CB.

Next, the bit sequence length in being processed more than describing.The sequence length of the bit sequence of original TB is considered as A. Performed by CRC adding devices 111 CRC bit addition after sequence be B (>=A).In addition, in response to turbo yards of code Long, the sequence length of r-th CB is Kr.The sequence length of the CW produced by CB connection units 116 is G '.From CW interleavers 118 The sequence length of the CW of output is G.G ' and G can be with identical.In addition, G ' may differ from G, because can be before CW interleavers 118 And perform filling after CW interleavers 118.

[4-2. interweaves and sets]

[4-2-1. weaving lengths]

For example, being the CW in Figure 10 by the weaving length that the controller 130 of the dispatching station 100 according to the present embodiment is controlled Sequence length.The length of the sequence from single interleaver (the CW interleavers 118 in the example shown in Figure 10) output is alternative in, The weaving length can be the sequence length of the sequence sum exported from the multiple interleaver when using multiple interleavers.

In common IDMA systems, bit sequence (TB in the example shown in Figure 10) and the FEC volumes for sending can be based on Code check determines weaving length G.When considering for IDMA to be applied to cellular system, it is desirable to based on the radio resource for distributing to user Amount (for example, the quantity of subcarrier, the quantity of Resource Block, quantity of space layer etc.) and modulation scheme (for example, QPSK, 16- QAM, 64-QAM, 256-QAM etc.) determine weaving length G.

Therefore, the controller 130 of the dispatching station 100 according to the present embodiment is based on the transmission that wireless communication unit 110 is performed The amount of available radio resource and the modulation scheme control weaving length for it.For example, controller 130 determines weaving length G so that weaving length G meets following formula.

[mathematic(al) representation 1]

G≤N_REQ_m... formula 1

Here, N_REIt is allocated to can be used for the number of the resource element of real data transmission among the radio resource of user Amount.In addition, Q_mIt is the bit multiplex quantity (it generally depends on modulation scheme) of each resource element.Meanwhile, when dispatching station 100 is adopted During with sending diversity, controller 130 may be in response to send the quantity N of diversity and adjustresources element_RE.For example, working as dispatching station 100 Using N_TDWhen rank sends diversity, can be used for the quantity N of the resource element of real data transmission_REIt is controlled to physical resource unit The 1/N of the quantity of element_TD。

Controller 130 can determine that value G so that realize that the equal sign of mathematic(al) representation 1 is used so as to the resource for making whole system Efficiency is maximized.

When wireless communication system 1 also uses multiplexing technology (such as, spread spectrum or spatial reuse skill in addition to IDMA Art) when, controller 130 can be based further on spreading factor and determine weaving length G.For example, controller 130 determines weaving length G, So that weaving length G meets following formula.

[mathematic(al) representation 2]

Here, SF is spreading factor.In addition, N_MIt is multiplexing quantity.Controller 130 can be to N_REIn the method for being counted Influence of the reflection for spreading factor and spatial reuse.

(filling treatment)

When the length of the list entries of interleaving treatment is not up to weaving length, controller 130 can control radio communication list Unit 110 performs filling.For example, if the sequence length G ' for being input to CW interleavers 118 in Fig. 10 is not up to weaving length G, Then controller 130 controls wireless communication unit 110 before the interleaving treatment performed by CW interleavers 118 or by CW interleavers Filling is performed after 118 interleaving treatments for performing.

For example, controller 130 can control wireless communication unit 110 performs filling to the list entries of interleaving treatment.For example, Work as G '<During G, before interleaving treatment is performed, CW interleavers 118 will be with N_pThe corresponding filler in=G-G ' positions is added to and is input to The input bit sequence of CW interleavers 118.

For example, be input to the input bit sequence of interleaver being

[mathematic(al) representation 3]

b′_k′, k '=0 ..., G ' -1 ... formula 3

Target bit sequence corresponding with the target of interleaving treatment is

[mathematic(al) representation 4]

b_k, k=0 ..., G-1 ... formula 4

And filling bit sequence is

[mathematic(al) representation 5]

p_k″, k "=0 ..., N_p- 1 ... formula 5

Filling bit sequence can be the pre- sequencing of all { 0 }, number all in { 1 }, any random { 0,1 } or { 0,1 } Row.The filling performed by CW interleavers 188 that reference picture 11 is described in this case is processed.

Figure 11 is the flow of the example of the flow for representing the filling treatment performed in the dispatching station 100 according to the present embodiment Figure.As shown in Figure 11, first, in step S202, CW interleavers 118 determine whether G '=G.

When it is determined that during G '=G (S202/ is), in step S204, CW interleavers 118 in statu quo make according to following formula With input bit sequence as target bit sequence.

[mathematic(al) representation 6]

b_k=b '_k, k=0 ..., G-1 ... formula 6

On the other hand, when it is determined that G '<During G (S202/ is no), CW interleavers 118 are used by that will fill out according to following formula Sequence that bit sequence is added to input bit sequence and obtains is filled as target bit sequence.

[mathematic(al) representation 7]

b_k=p_k, k=0 ..., N_p- 1,

Therefore, the sequence length of target bit sequence is changed into weaving length G, and the carry-out bit exported from CW interleavers 118 The sequence length of sequence is changed into G.

Then, in step S208, CW interleavers 118 perform interleaving treatment.

In addition, controller 130 can control wireless communication unit 110 performs filling to the output sequence of interleaving treatment.For example, Work as G '<During G, CW interleavers 118 will be with N after interleaving treatment is performed_pThe corresponding filler in=G-G ' positions is added to carry-out bit Sequence.The filling performed by CW interleavers 118 that reference picture 12 is described in this case is processed.

Figure 12 is the flow of the example of the flow for representing the filling treatment performed in the dispatching station 100 according to the present embodiment Figure.As shown in Figure 12, first, in step s 302, CW interleavers 118 perform interleaving treatment.

Then, in step s 304, CW interleavers 118 determine whether G '=G.

When it is determined that during G '=G (S304/ is), in step S306, CW interleavers 118 in statu quo export carry-out bit sequence.

On the other hand, when it is determined that G '<During G (S304/ is no), in step S308, the output of CW interleavers 118 will be by that will fill The sequence that bit sequence is added to the carry-out bit sequence and obtains.Therefore, the sequence length of carry-out bit sequence is changed into weaving length G。

The example of filling treatment has been described.

For example, used as the other method for realizing G '=G or G '≤G, de-rate matching unit 115 can adjust output bit sequence The sequence length of row.

(weaving length decision treatment)

For example, controller 130 uses the quantity N that can be used for the resource element that real data sends_RE and each resource element Bit multiplex quantity Q_m(digit) determines weaving length G.The mistake for processing this can be determined according to the type change of dispatching station 100 Journey.The example that treatment is determined according to the weaving length of the type of dispatching station 100 will be described below.

(A) it is the dispatching station that it distributes the radio resource for transmission by other devices

For example, dispatching station 100 is the UE in cellular system.The method that reference picture 13 is described to determine weaving length G.

Figure 13 is to represent that the weaving length performed in the dispatching station 100 according to the present embodiment determines showing for the flow for the treatment of The flow chart of example.

First, in step S402, wireless communication unit 110 receives control information and control information is decoded. For example, wireless communication unit 110 is received the control information that is sent from eNB using control channel and control information is solved Code.For example, control information may include the information of the available radio resource of transmission and modulation scheme on dispatching station 100.

Then, in step s 404, controller 130 obtains wireless on what is distributed for the transmission performed by dispatching station 100 The information of electric resources.For example, the information on radio resource is to indicate the Resource Block along frequency direction as resource allocation The information of quantity indicates the information which Resource Block has been allocated.

Thereafter, in step S406, controller 130 obtains the quantity N of the resource element that can be used for real data transmission_RE。 For example, controller 130 is obtained be consequently not used for the money of data is activation by being subtracted with the radio resource for distributing to dispatching station 100 The quantity of source element (such as, reference signal, synchronizing signal and control signal) and the quantity that obtains.In addition, when along frequency direction When the quantity of the resource of distribution is determined in advance (situation that such as, whole frequency band is assigned to dispatching station 100), for example, step Treatment in S404 and S406 can be omitted.

Next, in step S408, the control information that controller 130 is received from step S402 obtains instruction to be used for The information of the modulation scheme of the transmission performed by dispatching station 100.For example, the information for indicating modulation scheme can directly indicate to adjust CQI (CQI) in the information of scheme processed, such as LTE.In addition, it can be indirect to indicate the information of modulation scheme Indicate the information of modulation scheme, the modulation code set (MCS) in such as LTE.Wish advance in wireless communication system 1 Specify the information for indicating modulation scheme.

Then, in step S410, controller 130 is retrieved as each resource for the transmission distribution performed by controller 130 The digit Q of element_m.For example, controller 130 obtains each money from the modulation scheme that the information by being obtained in step S408 is indicated The digit Q of source element_m.When control information includes indicating the digit Q of each resource element_mInformation when, controller 130 can be from control The digit Q of each resource element of acquisition of information processed_m。

In addition, in step S412, controller 130 determines weaving length G.For example, controller 130 determines weaving length G It is set to G=N_RE×Q_m。

(B) dispatching station of radio resource of oneself distribution (or decision) for sending.

For example, dispatching station 100 is the eNB in cellular system.In addition, dispatching station 100 can be such as wireless communication system 1 Device, no radio resource is assigned to described device.The method that reference picture 14 is described to determine weaving length G.

Figure 14 is to represent that the weaving length performed in the dispatching station 100 according to the present embodiment determines showing for the flow for the treatment of The flow chart of example.Described in this flow when assuming that in the case of one-to-one transmission perform for user i transmission when Processing example.In the case of one-to-many transmission, there are multiple user index i.

As shown in Figure 14, first, in step S502, controller 130 is obtained on being used for for use by dispatching station 100 The information of the radio resource of the transmission of family i.For example, the information on radio resource is indicated along frequency direction as resource The information of the quantity of the Resource Block for using indicates the information which Resource Block used.

Then, in step S504, controller 130 obtains the resource element that can be used for sending for the real data of user i The quantity N of element_RE.For example, controller 130 is obtained be consequently not used for by being subtracted with the radio resource used by dispatching station 100 The quantity of the resource element (such as, reference signal, synchronizing signal and control signal) of data is activation and the quantity that obtains.When along frequency When the quantity of the resource of rate direction distribution is determined in advance, the treatment in step S502 and S504 can be omitted.

Then, in step S506, controller 130 obtains the letter for indicating the modulation scheme for the transmission for user i Breath.For example, acquisition of information of the controller 130 with reference to storage in the storage unit 120 indicates the information of modulation scheme.

Next, in step S508, controller 130 obtains each resource element for the transmission for user i Digit Q_m.For example, controller 130 obtains each resource element from the modulation scheme that the information by being obtained in step S408 is indicated Digit Q_m.Controller 130 can direct access indicate the digit Q of each resource element_mInformation.

Then, in step S510, controller 130 determines weaving length G.For example, controller 130 determines weaving length G It is set to G=N_RE×Q_m。

The example that weaving length determines the flow for the treatment of has been described.

As indicated above, it is desirable in wireless communication system 1 preassign indicate modulation scheme information, such as CQI or MCS.The example of the specification of MCS is illustrated in following table 1.

Table 1

In table 1 more than, first row indicates MCS indexes, and secondary series corresponds to the digit Qm of each resource element.

In addition, the example of the specification of CQI is illustrated in following table 2.

[table 2]

In table 2 more than, first row indicates CQI indexes, secondary series to indicate modulation scheme, and the 3rd row to correspond to often The digit Q of individual resource element_m。

[4-2-2. intertextures pattern]

The controllable intertexture performed by wireless communication unit 110 of the controller 130 of the dispatching station 100 according to the present embodiment Intertexture pattern in reason.In IDMA, make intertexture pattern different by for dispatching station, it is possible to achieve sending signal is multiplexed and connects Receive the Signal separator in station.Thus, for example, the controller 130 of the dispatching station 100 according to the present embodiment is secondary according to what is resend Numerical control intertexture pattern.For example, controller 130 determines intertexture pattern by following formula.

[mathematic(al) representation 8]

Here, I_UserIt is user identifier, such as ID or radio network temporary identifier (RNTI).G is to interweave Length.I_CellIt is cell ID, such as cell-RNTI.S_TbsIt is the digit (transport block size) of correspondence TB.In addition, S_TbsCan be I in the specification of MCS_TBS。P_HarqIt is the process ID of mixed automatic repeat request (HARQ).N_RetxIt is resending for correspondence TB Number of times, such as 0 in the case of initial transmission and in the case where first time resends 1.SFN is for resending Radio resource System Frame Number.O_IntIt is the deviant considered in intertexture pattern.For example, this value can by eNB devices or Other devices in wireless communication system 1 are specified.Wish O_Int<G.Because, when being equal to or during value more than G, lead to Modular arithmetic is crossed to eliminate the deviant.

Formula 8 above is represented：M be changed into carry-out bit sequence n-th of the input bit sequence of CW interleavers 118, As shown in Figure 15.Figure 15 represents the intertexture mode control method according to the present embodiment.According to the formula, even if with dynamic In the system of the variable weaving length G of state, intertexture pattern is also qualitatively specified.Due to specifying intertexture pattern according to the formula, So dispatching station 100 can not store all intertexture patterns related to variable weaving length G, and memory cell can be reduced Storage load in 120.

In addition, as shown in above formula 8, controller 130 can be according to the times N for resending_RetxOr system frame number SFN changes Become the intertexture pattern for resending every time.By changing the intertexture pattern for resending every time so that intertexture pattern randomization, control Device processed 130 can obtain diversity and reduce interference.

Controller 130 can pass through distinct methods according to sending direction (such as, up-link, downlink and D2D communication) Determine intertexture pattern.For example, controller 130 can determine intertexture pattern according to sending direction using different formulas.In addition, such as following Formula shown in, controller 130 can be used by by indicate sending direction parameter L_dThe formula for being added to formula 8 and obtaining is determined Surely interweave pattern.

[mathematic(al) representation 9]

Ld is the parameter with the value for depending on related sending direction.For example, the parameter there can be certain value, such as exist There is value 0 in the case of downlink, in the uplink case with value 10, or have in the case where D2D communicates Value 100.

CW interleavers 118 can be configured as single interleaver, or including multiple interleavers.Hereinafter, institute in CW interleavers 118 Including multiple interleavers be referred to as sub- interleaver.Controller 130 can be controlled by switching the sub- interleaver of execution interleaving treatment Intertexture pattern processed.Hereinafter, by the such example of the description of reference picture 16 to 18：CW interleavers 118 include being formed in multiple levels Many sub- interleavers.

Figure 16 is the block diagram of the internal structure for representing the CW interleavers 118 according to the present embodiment.Figure 16 illustrates In example, CW interleavers 118 include the sub- sub- interleaver of the interleaver 1182, third level of the sub- interleaver 1181, second level of the first order 1183rd, the sub- interleaver 1184 of the fourth stage and PHY layer controller 1185.The sub- interleaver 1181 of the first order is common interleaver.Second The sub- interleaver 1182 of level is the interleaver with the pattern that can be changed according to ID and/or cell ID.The sub- interleaver of the third level 1183 is the interleaver with the pattern that can be changed according to SFN.The sub- interleaver 1184 of the fourth stage be have can according to send time The interleaver of number and/or the pattern of the number of times change for resending.PHY layer controller 1185 is based on for example being obtained from control channel Control information correspondence parameter is input to included sub- interleaver in CW interleavers 118.For example, PHY layer controller 1185 ID and/or cell ID are input to the sub- interleaver 1182 in the second level.In addition, SFN is input to by PHY layer controller 1185 The sub- interleaver 1183 of three-level.In addition, the number of times of transmission and/or the number of times for resending are input to by PHY layer controller 1185 The sub- interleaver 1184 of level Four.

As shown in the example of Figure 16, it is desirable to which included sub- interleaver uses different parameters conduct in CW interleavers 118 Input performs different interleaving treatment.Therefore, controller 130 according to circumstances can more easily control use/unuse to be handed over per height Knit device.Meanwhile, the order of sub- interleaver is optional, and the quantity and |input paramete of sub- interleaver are also optional.In addition, Sub- interleaver can have any weaving length, and with identical weaving length or different weaving lengths.For example, the length that interweaves Degree can be initially set to G ', and change into G in the centre for the treatment of when filling treatment is performed.Additionally, it is desirable that sub- interleaver With identical weaving length.

Figure 17 is the block diagram of the internal structure for representing the CW interleavers 118 according to the present embodiment.Join by according to input Number transmission |input paramete, the CW interleavers 118 shown in Figure 17 can in the execution of the interleaving treatment of every sub- interleaver treatment and Switch between not the performing of interleaving treatment.

Figure 18 is the block diagram of the internal structure for representing the CW interleavers 118 according to the present embodiment.The CW shown in Figure 18 Interleaver 118 has many combinations of sub- interleaver in each grade.For example, CW interleavers 118 have first in the first stage The combination of the sub- interleaver 1181A and 1181B of level.In addition, CW interleavers 118 have the sub- interleaver in the second level in the second level The combination of 1182A and 1182B.In addition, CW interleavers 118 have the sub- interleaver 1183A's and 1183B of the third level in the third level Combination.The combination with the sub- interleaver 1184A and 1184B of the fourth stage in the fourth stage of CW interleavers 118.CW interleavers 118 can Any sub- interleaver using the combination of the sub- interleaver at different levels switches interleaving treatment.

When CW interleavers 118 are formed in multiple levels, various |input parametes are considered for every sub- interleaver.Below The display parameters of table 3 example.Here, it is desirable to which the parameter with different update interval is imported into each sub- interleaver.At this In the case of kind, CW interleavers 118 can over time and suitably change intertexture pattern.In addition, CW interleavers 118 can be using little Other information change the structure of sub- interleaver.

[table 3]

[intertexture 4-3. related to resending is set]

The controller 130 of dispatching station 100 can be set according to treatment Type Control intertexture is resend.Controller 130 can root Type Control weaving length or intertexture pattern are processed according to resending.Hereinafter, the intertexture related to HARQ will be first described to set.

[4-3-1. self adaptations/non-self-adapting]

First, two kinds of HARQ (adaptive HARQ and non-self-adapting HARQ) is considered as resending showing for type Example.Adaptive HARQ is that have the HARQ that can be directed to the modulation scheme for resending change every time.When dispatching station 100 is using adaptive When answering HARQ, dispatching station 100 can increase the free degree of resources control.However, dispatching station 100 performs use during resending Sent in the signal of specified modulation scheme.On the other hand, non-self-adapting HARQ is that have fixed modulation side during resending The HARQ of case.When dispatching station 100 is using non-self-adapting HARQ, even if the free degree of resources control reduces, dispatching station 100 also can Enough signal transmissions omitted for specified modulation scheme.

Incidentally, when dispatching station 100 using HARQ when, it is desirable to TB sizes (digit of each TB) with as again TB sizes during the preceding once transmission of the TB for sending target are identical, because the signal combination in receiving station 200 becomes simple.

Hereinafter, reference picture 19 is described to determine the example for the treatment of according to the weaving length of HARQ types.

Figure 19 is to represent that the weaving length performed in the dispatching station 100 according to the present embodiment determines showing for the flow for the treatment of The flow chart of example.

As shown in Figure 19, first, in step S602, whether the TB that controller 130 determines to send target is most initial The TB for sending.

When TB is determined as TB (S602/ is) being originally sent, in step s 604, controller 130 is by being used for The initial process for sending determines weaving length.Here, retouched as an example in Figure 13 and 14 for the initial procedural representation for sending The treatment stated.

When TB is determined as TB (S602/ is no) for resending, in step S606, controller 130 determines whether Using adaptive HARQ.The criterion for the determination will be described below.

When it is determined that during using adaptive HARQ (S606/ being), the treatment advances to step S604, and controller 130 is logical Cross and determine weaving length for the initial process for sending.Because, in the case of adaptive HARQ, modulation scheme can be changed Or the quantity of resource element.

On the other hand, when it is determined that during using non-self-adapting HARQ (S606/ is no), in step S608, controller 130 determines The quantity N of available resource elements_REThe quantity N of the available resource elements whether being different from during preceding once transmission_RE.Because i.e. The Resource Block of equal number is set to be used, the quantity of available resource elements also alterable, so performing the determination.

When it is determined that the quantity of available resource elements is different from the quantity of the available resource elements during preceding once transmission When (S608/ is), the treatment advances to step S604, and controller 130 determines to interweave by for the initial process for sending Length.

On the other hand, when it is determined that the quantity and the number of the available resource elements during preceding once transmission of available resource elements Measure identical (S608/ is no) when, in step S610, controller 130 again using with it is preceding once send during intertexture it is long Degree identical weaving length.

Hereinafter, reference picture 20 is described for determining whether in step S606 using the criterion of adaptive HARQ.Here, It is that it distributes dispatching station (such as, in cellular system for the radio resource for sending that dispatching station 100 is considered as by other devices UE).When dispatching station 100 is dispatching station (such as, the cellular system of radio resource of oneself distribution (or decision) for sending In eNB) when, can based on it is any determination criterion determine whether to use adaptive HARQ.

Figure 20 is to represent that the HARQ types performed in the dispatching station 100 according to the present embodiment determine showing for the flow for the treatment of The flow chart of example.

As shown in Figure 20, first, in step S702, controller 130 is notified from by eNB etc. using such as control channel Control information obtain MCS.Here, wireless communication system 1 can be used with the specification of the MCS shown in upper table 1.

Then, controller 130 determine correspondence TBS whether be the MCS shown in table 1 specification in " reservation ".It is alternative in It is determined that whether correspondence TBS is " reservation ", controller 130 can determine that whether correspondence TBS is particular value.

When correspondence TBS is not " reservation " (S704/ is no), in step S710, controller 130 determines to use self adaptation HARQ。

On the other hand, when correspondence TBS is " reservation " (S704/ is), in step S706, controller 130 determines correspondence Order of modulation whether be the MCS shown in table 1 specification in " reservation ".It is alternative in whether determination corresponding modulating exponent number is " to protect Stay ", controller 130 can determine that whether corresponding modulating exponent number is particular value.

When corresponding modulating exponent number is not " reservation " (S706/ is no), in step S710, controller 130 is determined using certainly Adapt to HARQ.

On the other hand, when corresponding modulating exponent number is " reservation " (S706/ is), in step S708, controller 130 determines Using non-self-adapting HARQ.

In addition, when the mark of which kind of HARQ being notified of in indicating that adaptive HARQ and non-self-adapting HARQ will be used When, dispatching station 100 can notify to determine which kind of HARQ used based on described.

Have contemplated that adaptive HARQ and non-self-adapting HARQ.

[4-3-2.CC/IR]

Next, pursuit merges (CC) and incremental redundancy (IR) is considered as resending another example of type.Hereinafter, adopt It is referred to as the HARQ with CC with the HARQ of CC, and HARQ using IR is referred to as the HARQ with IR.

For example, the controller 130 of dispatching station 100 can control wireless communication unit 110 using CC as resending treatment Type.In non-orthogonal multiple access system (such as, IDMA), duplicate detection treatment is conciliate in many cases for receiving station 200 Code treatment.Therefore, when dispatching station 100 is using CC, in the treatment for initially detecting the signal for resending, receiving station 200 can To be used to disturb elimination etc. from the position log-likelihood ratio (LLR) of the signal acquisition for having been received before preceding once transmission.Certainly, Controller 130 can control wireless communication unit 110 using IR as resending treatment type.However, in IR, even if working as TB When initially identical, when execution resends, for the coding sequence for resending selection can also be different.Therefore, When dispatching station 100 is using IR, receiving station 200 is difficult in the treatment for initially detecting the signal for resending using until previous The result of the secondary decoding for sending the signal for receiving.

Hereinafter, reference picture 21 is described to resend the example that type determines treatment.

Figure 21 is to represent the flow that type determines treatment that resends performed in the dispatching station 100 according to the present embodiment Example flow chart.

As shown in Figure 21, first, in step S802, whether the CW or TB for being determined as transmission target resend CW or TB.

When it is determined that CW or TB are the CW or TB (S802/ is) that resend, in step S804, controller 130 determines Whether target CW or TB are sent using IDMA.For example, controller 130 can determine that uses IDMA in the case of one-to-many communication, And determination does not use IDMA in the case of One-to-one communication.

When it is determined that during using IDMA (S804/ being), in step S806, controller 130 is determined using the HARQ with CC.

On the other hand, when it is determined that not using IDMA (S804/ is no), in step S808, controller 130 is determined using tool There is the HARQ of IR.

In addition, when determining that target CW or TB is originally sent (S802/ is no), in step S810, controller 130 determines Do not use HARQ.

Although controller 130 using CC and is not using IDMA when IDMA be used to resend in the above description Shi Caiyong IR, but CC can be all used in both cases.In addition, controller 130 can be by it is determined that criterion is used for step S804 In determination.For example, controller 130 can use CC when non-orthogonal multiple access system be used to resend, and at it IR is used in the case of it.In addition, ought send and receive the CW's for resending or TB in other CW or TB identical resources During at least a portion, controller 130 can use CC, and when CW or TB is sent and received in different resource, controller 130 IR can be used.

[execution/non-execution that 4-3-3. interweaves]

Whether the controller 130 of dispatching station 100 can be whether the sequence control for resending uses according to transmission sequence IDMA performs radio communication.Specifically, controller 130 may be in response to whether CW is possibly retransmission and in the execution of interleaving treatment Switch and not the performing of interleaving treatment between.Wish between dispatching station 100 and receiving station 200 it is shared in advance resend/just Originate the relation between the execution/non-execution sent and interweave.Not performing for interleaving treatment can be mutually the same using having The execution of the interleaving treatment of the interleaver of list entries and output sequence.

For example, when the sequence for sending is the sequence for resending, controller 130 can control wireless communication unit 110 to be made Radio communication is performed with IDMA.When it is the sequence being originally sent to send sequence, controller 130 can control wireless communication unit 110 perform radio communication in the case where IDMA is not used.Here, controller 130 can be according to as resending connecing for target The quantity for receiving station 200 controls whether to use IDMA to perform radio communication.For example, as to resend the receiving station 200 of target Quantity it is larger when, controller 130 can control wireless communication unit 110 and use IDMA, and when existing as resending mesh During the single receiving station 200 of target, controller 130 can control wireless communication unit 110 and not use IDMA.In this case, send out See off 100 can switch according to the possibility of the interference in receiving station 200 between using IDMA and not IDMA is not used.

Used as another control example, when it is the sequence for resending to send sequence, controller 130 can control radio communication Unit 110 performs radio communication in the case where IDMA is not used, and when it is the sequence being originally sent to send sequence, control Device 130 can control wireless communication unit 110 and perform radio communication using IDMA.

Dispatching station 100 to receiving station 200 notify indicate send sequence whether be the sequence for resending information.For example, Represent that target CW is originally sent or the position that resends marks by setting in target control channel, dispatching station 100 can be to Whether receiving station 200 notifies perform intertexture.For example, the new data in down link control information (DCI) in control channel refers to Show that symbol (NDI) can be the example of position mark./ initial transmission is resend when being shared between dispatching station 100 and receiving station 200 And interweave execution/non-execution between relation when, this is effective.In addition, being alternative in preceding rheme mark or except preceding rheme Outside mark, the settable position mark for directly indicating to perform or do not perform intertexture of dispatching station 100.

When the CW interleavers 118 of wireless communication unit 110 as shown in Figure 17 are formed in multiple levels, controller 130 can switch in the execution of the interleaving treatment by every individual sub- interleaver and between not performing, as shown in Figure 22.

Figure 22 is between representing the execution of the interleaving treatment performed in the dispatching station 100 according to the present embodiment and not performing The flow chart of the example of the flow of the treatment of switching.

As shown in Figure 22, first, in step S902, whether the CW for being determined as transmission target is originally sent CW。

When it is determined that CW is originally sent (S902/ is), in step S904, controller 130 determines to perform predetermined intertexture Treatment.For example, controller 130 is determined by the sub- interleaver of target among many sub- interleavers included in CW interleavers 118 (for example, the sub- interleaver 1181 of the first order shown in Figure 17) performs interleaving treatment.

Then, in step S906, controller 130 produces the control letter for indicating the predetermined interleaver treatment to be performed Breath.For example, controller 130 is set in control channel corresponding with target CW and being indicated the marks that are originally sent of target CW or being referred to Show the mark that the predetermined interleaving treatment has been performed.

On the other hand, when it is determined that CW is possibly retransmission (S902/ is no), in step S908, controller 130 determines not hold The row predetermined interleaving treatment.

Then, in step S910, controller 130 produces the control letter for indicating the predetermined interleaver treatment not to be performed Breath.For example, controller 130 is set in control channel corresponding with target CW and being indicated the marks that are possibly retransmission of target CW or being referred to Show the mark that the predetermined interleaving treatment is not performed.

For every sub- interleaver being formed in multiple levels, above-mentioned flow is repeated.During the repetition of the flow, For example in addition to for determining the criterion whether CW is originally sent to upper table 3 in the related determination of any parameter for showing Criterion is used as being fixed really then in step S902.In addition, step S904 and S906 can be exchanged with step S908 and S910.

When the CW interleavers 118 of wireless communication unit 110 as shown in Figure 18 are formed in multiple levels, controller 130 can switch interleaving treatment by sub- interleaver, as shown in Figure 23.

Figure 23 is between representing the execution of the interleaving treatment performed in the dispatching station 100 according to the present embodiment and not performing The flow chart of the example of the flow of the treatment of switching.

As shown in Figure 23, first, in step S1002, whether the CW for being determined as transmission target is originally sent CW。

When it is determined that CW is originally sent (S1002/ is), in step S1004, controller 130 determines to perform predetermined friendship Knit treatment A.For example, controller 130 determine by CW interleavers 118 every one-level in included many combinations of sub- interleaver Any sub- interleaver (for example, the sub- interleaver 1181A of the first order shown in Figure 18) perform interleaving treatment.

Then, in step S1006, controller 130 produces the control for indicating the predetermined interleaver treatment A to be performed Information.For example, controller 130 set in control channel corresponding with target CW indicate the marks that are originally sent of target CW or The mark for indicating the predetermined interleaving treatment A to be performed.

On the other hand, when it is determined that CW is possibly retransmission (S1002/ is no), in step S1008, controller 130 determines to hold The predetermined interleaving treatment B of row.For example, controller 130 determine by CW interleavers 118 every one-level in included many sub- interleavers Combination in from the different sub- interleaver of sub- interleaver selected in step S1004 (for example, the first order shown in Figure 18 Sub- interleaver 1181B) perform interleaving treatment.

Next, in step S1010, controller 130 produces the control for indicating the predetermined interleaver treatment B to be performed Information processed.For example, controller 130 sets the mark for indicating target CW to be possibly retransmission in control channel corresponding with target CW Or the mark that the instruction predetermined interleaving treatment B has been performed.

Each combination of sub- interleaver for being formed in multiple levels, repeats above-mentioned flow.The repetition of the flow Period, related to any parameter in addition to for determining the criterion whether CW is originally sent is fixed really, is used as step Fixed really then in rapid S1002.According to the flow, dispatching station 100 can use suitable intertexture pattern according to resending, Thus the transmission quality and the quality of reception in resending further are improved.

Dispatching station 100 has been described.When switching the execution of interleaving treatment in dispatching station as described above and not performing, receive 200 are stood using the corresponding setting that deinterleaves.Hereinafter, reference picture 24 is described the setting control that deinterleaves in receiving station 200 Treatment.

Figure 24 is the flow for representing the setting control process that deinterleave performed in the receiving station 200 according to the present embodiment The flow chart of example.This flow is based on such hypothesis：Whether dispatching station 100 is originally sent at each in response to target CW The execution of the interleaving treatment of sub- interleaver and switch between not performing, as shown in Figure 22.

As shown in Figure 24, first, in step S1102, controller 230 obtains control information.For example, radio communication list Unit 110 receives the control information sent from eNB using control channel, and control information is decoded, and control information is defeated Go out to controller 230.

Then, in step S1104, controller 230 obtains NDI.Then, in step S1106, controller 230 determines Whether there is provided the mark of NDI.

When it is determined that there is provided NDI mark (S1106/ is) when, in step S1108, controller 230 determine target CW quilts It is originally sent.Thereafter, in step S1110, controller 230 determines to perform predetermined interleaving treatment to target CW.

On the other hand, when it is determined that being not provided with mark (S1106/ is no) of NDI, in step S1112, controller 230 is true The CW that sets the goal is possibly retransmission.Then, in step S1114, controller 230 determines not perform at predetermined intertexture target CW Reason.

Then, in step S1116, controller 230 is using the corresponding setting that deinterleaves.

In the side of dispatching station 100, for every sub- interleaver being formed in multiple levels, above-mentioned flow is repeated.Repeating During the flow, really fix related to any parameter in addition to the criterion of the mark for determining whether to be provided with NDI then may be used It is used as being fixed really then in step S1106.

(basic structure of wireless communication unit 210)

Figure 28 is the example of the logical construction of the wireless communication unit 210 for representing the receiving station 200 according to the present embodiment Block diagram.Figure 28 represents the example of the structure of a part for wireless communication unit 210, wherein the signal received from dispatching station 100 It is decoded.As shown in Figure 28, wireless communication unit 210 include channel estimator 211, detector 212, CW deinterleavers 213, CW decoders 214, CRC decoders 215, CW interleavers 216, soft bit buffer 217 and PHY layer controller 218.

The included reference signal from the signal for receiving of channel estimator 211 estimate dispatching station 100 and receiving station 200 it Between radio propagation channel state.Channel estimator 211 will indicate the letter of the radio propagation channel status estimated Road information output is to detector 212.

The number included in detecting the signal for receiving using the channel information exported from channel estimator 211 of detector 212 According to part.This detection process correspond to the subscriber signal or layer signal or subscriber signal that are multiplexed in the signal for separating and receiving and The treatment of both layer signals.Hereinafter, detector 212 is referred to as multi-user/multilayer detector 212.Wish with corresponding CW Position log-likelihood ratio (value in LLR, such as scope of [- 1 to+1]) form output separate signal.In addition, can be according to The signal that the form output of the hard decision bit (- 1 or+1) of correspondence CW is separate.

According to TB or CW perform decoding process corresponding with the weaving length and intertexture pattern that are used in dispatching station 100 with Output bit value.Here, will be described with the decoding process of the TB or CW of index i.

CW deinterleavers 213 (are deinterleaved using the setting that deinterleaves corresponding with the intertexture setting used in dispatching station 100 Length and the pattern that deinterleaves) perform the treatment that deinterleaves.Here, the length that deinterleaves represents the sequence for being input to CW deinterleavers 213 Length.The CW for deinterleaving is given CW decoders 214 ((A) in the accompanying drawing) by CW deinterleavers 213.

CW decoders 214 perform fec decoder treatment to the CW that each deinterleaves.The CW outputs that CW decoders 214 will be decoded Give CRC decoders 215 ((B) in the accompanying drawing).In addition, when crc error is detected by CRC decoders 215, CW decoders The place value ((C) in the accompanying drawing) of 214 feedback correspondence CW.Feedback target is CW interleavers 216 or soft bit buffer 217.Will be The internal structure of CW decoders 214 described in detail below.

CRC decoders 215 perform CRC detection process to the CW or TB of fec decoder.When crc error is detected, CRC solutions The CW or TB of the code output decoding of device 215.

216 couples of CW fed back from CW decoders 214 or soft bit buffer 217 of CW interleavers perform interleaving treatment, and will The CW of intertexture is exported to multi-user/multilayer detector 212.CW interleavers 216 are using in dispatching station 100 corresponding with transmission source The intertexture for using sets and performs interleaving treatment.Here, multi-user/multilayer detector 212 exports to CW deinterleavers 213 simultaneously CW And a series of signal treatment for receiving feedback from CW interleavers 216 can be repeated, until successfully decoded.For example, decoding process can Repeated, until the number of times that can't detect the crc error of target CW or TB or repeat reaches maximum times.The solution of this repetition Code treatment is referred to as turbo detections or turbo decoding process.

Soft bit buffer 217 has such function：Accumulate up to the preceding decoded result for once receiving, and in dispatching station 100 perform the decoded result that be will build up on when resending feeds back to multi-user/multilayer detector 212.For example, soft bit buffer The position LLR of 217 accumulation CW.In addition, soft bit buffer 217 will be up to preceding in the treatment decoded to the signal for resending The decoded result for once receiving is exported to CW interleavers 216.Therefore, when dispatching station 100 is using CC, wireless communication unit 210 Can be using until the preceding decoded result perform decoding for once receiving be processed.When dispatching station 100 is using IR, soft bit buffer 217 can not carry-out bit LLR or output pre-determined bit LLR (such as, for example all positions are 0 sequences).

PHY layer controller 218 is in response to the control information adjusting parameter that is obtained from control channel.For example, PHY layer controller 218 (distribute resource, modulator approach, volume according to the transmission parameter of decoding the target CW or TB for being applied to be sent by control channel Code method or decoding rate etc.) set wireless communication unit 210 each block parameter.In addition, PHY layer controller 218 is solved from CW Code device 214 obtains the fec decoder result of CW, TB or CB, and the CRC for obtaining CB, TB or CB from CRC decoders 215 detects knot Really.PHY layer controller 218 is based on fec decoder result and CRC testing results control the decoding process of above-mentioned repetition.

When the successfully decoded of target CW or TB, wireless communication unit 210 returns to ACK corresponding with transmission source Dispatching station 100.On the other hand, when target CW or TB decoding fail when, wireless communication unit 210 by NACK response return to The corresponding dispatching station 100 of transmission source.Dispatching station 100 resends treatment in response to ACK and NACK response controls.

The example of the structure of wireless communication unit 210 has been described.Next, reference picture 29 and 30 is described into receiving station 200 In decoding process basic operation treatment.

(the basic operation treatment of wireless communication unit 210)

Figure 29 and 30 is that the explanation of the example of the flow for representing the decoding process in the receiving station 200 according to the present embodiment is shown Figure.The flow shown in Figure 29 and 30 is connected by the symbol A and B shown in the accompanying drawing.

As shown in Figure 29, first, in step S1202, PHY layer controller 218 determine target CW whether multi-user/ Initially detected in multilayer detection.For example, PHY layer controller 218 determines the detection process mesh of multi-user/multilayer detector 212 Mark is the signal or the output sequence from CW interleavers 216 for receiving.

When it is determined that target CW is by initially detection (S1202/ is), in step S1204, PHY layer controller 218 determines mesh Mark CW whether be HARQ initial transmission.

When it is determined that target CW is initial transmission (S1204/ is), in step S1206, PHY layer controller 218 is determined not Position LLR is fed back into multi-user/multilayer detector 212.Soft bit buffer 217 can not carry-out bit LLR or output pre-determined bit LLR (such as, for example all positions are 0 sequences).

When it is determined that target CW is not initial transmission (S1204/ is no), in step S1208, PHY layer controller 218 determines Whether the target CW for resending is identical with the former CW for sending.For example, when dispatching station 100 is using CC, PHY layer controller 218 determine that the target CW for resending is identical with the former CW for sending, and when dispatching station 100 is using IR, PHY layer controller 218 determine that the target CW for resending is different from the former CW for sending.

When it is determined that the target CW for resending is with CW identical (S1208/ is) of former transmission, PHY layer controller 218 is determined The fixed position LLR for using HARQ corresponding with the target CW in preceding once reception is used as to the anti-of multi-user/multilayer detector 212 Feedback.Therefore, the position LLR of HARQ corresponding with the target CW in preceding once reception is exported and is given CW interleavers by soft bit buffer 217 216.On the other hand, when it is determined that the target CW for resending is from CW different (S1208/ is no) of former transmission, the treatment is advanced To step S1206.

When it is determined that target CW is not by initially detection (S1202/ is no), in step S1212, PHY layer controller 218 is determined It is fixed to use position LLR corresponding with the target CW in preceding once decoding as the feedback to multi-user/multilayer detector 212.Therefore, CW decoders 214 export the CW of decoding to CW interleavers 216.

Then, in step S1214, the feedback of the position LLR corresponding with target CW of CW interleavers 216 pairs is interleaved.

Then, in step S1216, multi-user/multilayer detector 212 performs multi-user/multilayer detection process, such as Figure 30 Shown in.

Then, in step S1218, CW deinterleavers 213 deinterleave to the position LLR of target CW.

Thereafter, in step S1220, CW decoders 214 are decoded to target CW.

Next, in step S1222, soft bit buffer 217 preserves corresponding with the target CW exported from CW decoders 214 Position LLR.

Then, in step S1224, CRC decoders 215 pairs perform CRC from the decoded result position of the output of CW decoders 214 Verification.

When crc error (S1226/ is) is detected, in step S1228, PHY layer controller 218 is determined to being at present Whether the number of times of the execution of the detection process of the multi-user/multilayer detector 212 for only being performed for target CW is less than predetermined maximum Number of times.

When it is determined that the number of times of the execution of detection process is less than predetermined maximum times (S1228/ is), the treatment is another It is secondary to return to step S1202, and perform the decoding process of repetition.

On the other hand, when it is determined that the number of times of the execution of detection process reaches predetermined maximum times (S1228/ is no), In step S1230, wireless communication unit 210 returns to the NACK signal for target CW.

When crc error (S1226/ is no) is not detected by, in step S1232, wireless communication unit 210 is returned and is directed to mesh Mark the ack signal of CW.

The basic operation treatment of the decoding process in receiving station 200 has been described.CW in the accompanying drawing can be changed to TB.

(internal structure of CW decoders 214)

Hereinafter, reference picture 31 is described the internal structure of CW decoders 214.

Figure 31 is the block diagram of the example of the logical construction for representing the CW decoders 214 according to the present embodiment.As in Figure 31 Shown, CW decoders 214 go matching unit 2141, HARQ assembled units 2142, FEC to solve including CB cutting units 2140, speed Code unit 2143, CRC decoding units 2144, CB connection units 2145, soft bit buffer 2146, de-rate matching unit 2147 and CB Connection unit 2148.As shown in Figure 28, CW decoders 214 can be the block with an input and two outputs.In Figure 31 (A), (B) and (C) (A), (B) and (C) for corresponding respectively in Figure 28.(B) of Figure 31 is the CRC detections of the CW or TB of decoding The output for the treatment of, and (C) of Figure 31 is output for being preserved by soft bit buffer 217 and to multi-user/multilayer detection The feedback of device 212.

Each CW in multi-user/multilayer detector 212 separate is divided into one or more by CB cutting units 2140 Correspondence CB.Therefore, treatment below is the treatment in units of CB.

Speed goes matching unit 2141 to go matching treatment to compensate the position pierced through in dispatching station 100 according to speed.

When it is the CB for resending according to HARQ to process target CB, HARQ assembled units 2142 perform such place Reason：Combination is until place value (for example, LLR) and the currently received position of the preservation of a preceding decoding process.The place value is stored in In soft bit buffer 2146.In the case of initial transmission, HARQ assembled units 2142 do not perform the combined treatment.

Fec decoder unit 2143 is used and the FEC corresponding coding/decoding methods of coding used in dispatching station 100 from reception Position reproduces and sends position.For example, when FEC codings are that turbo is encoded, fec decoder unit 2143 is decoded using turbo, when FEC is compiled When code is convolutional encoding, fec decoder unit 2143 uses Veterbi decoding, and when FEC codings are that LDPC is encoded, FEC solutions Code unit 2143 uses and accumulates message transmission or belief propagation.

CRC decoding units 2144 perform CRC detection process to each CB.It is being not detected by crc error or is reaching to make a reservation for most Before big number of times, fec decoder unit 2143 repeats fec decoder treatment.

CB connection units 2145 combine one or more CB from the output of CRC decoding units 2144, and export combination CB ((B) in the accompanying drawing).

Soft bit buffer 2146 stores the bit sequence (soft bit or position LLR) decoded by fec decoder unit 2143, and should Bit sequence is exported to HARQ assembled units 2142 or de-rate matching unit 2147.In addition, can be separately provided for HARQ groups Close the soft bit buffer 2146 and the soft bit buffer for the output to de-rate matching unit 2147 of the output of unit 2142 2146。

2147 couples of CB (position LLR) exported from fec decoder unit 2143 or soft bit buffer 2146 of de-rate matching unit hold Row rate-matched.

CB connection units 2148 combine one or more CB from the output of de-rate matching unit 2147, and export combination CB ((C) in the accompanying drawing).

Figure 32 to 35 is that the explanation of the example of the flow for representing the decoding process in the receiving station 200 according to the present embodiment is shown Figure.The flow shown in Figure 32 to 34 is connected by the symbol A to F shown in the accompanying drawing.

As shown in Figure 32, first, in step S1302, PHY layer controller 218 determines whether to perform target CW One or more multi-users/multilayer detection process.

When it is determined that during executed one or more multi-users/multilayer detection process (S1302/ is), in step S1304, CW is divided into one or more CB by CB cutting units 2140.This treatment is corresponding to the input (A) shown in Figure 31.Such as Figure 32 Shown in, perform following treatment for each CB.

Then, in step S1306, PHY layer controller 218 determines whether once to be received including preceding in target CB The result without crc error is obtained in reception.

When it is determined that having obtained result (S1306/ is) without crc error, in step S1308, PHY layer controller 218 think that target CB does not have crc error.

On the other hand, when it is determined that not obtaining result (S1306/ is no) without crc error, in step S1310, speed Go matching unit 2141 to align LLR execution speed and go matching treatment.

Then, in step S1312, PHY layer controller 218 determines whether target CB is resending according to HARQ CB。

When it is determined that target CB is CB (S1312/ is) for resending, in step S1314, HARQ assembled units 2142 Position LLR in once being received before being obtained from soft bit buffer 2146.When it is determined that target CB is the CB that is originally sent (S1312/ is no) When, the treatment advances to step S1318, will be described below step S1318.

Then, in step S1316, HARQ assembled units 2142 combine current goal position LLR and the preceding position for once receiving LLR.For example, HARQ assembled units 2142 can perform addition, average, weighted average or IR combination.

Thereafter, in step S1318, fec decoder unit 2143 performs fec decoder.

Then, in step S1320, soft bit buffer 2146 is preserved and the decoded result from fec decoder unit 2143 Corresponding soft bit (position LLR).

Then, in step S1322, decoded result position of the CRC decoding units 2144 pairs from fec decoder unit 2143 is held Row CRC check.

When there is crc error (S1324/ is), in step S1326, up to the present PHY layer controller 218 determines Whether the number of times of the execution of the fec decoder performed for target CB is less than predetermined maximum times.

When it is determined that the number of times of the execution of the fec decoder for up to the present performing is less than the predetermined maximum times (S1326/ It is) when, the treatment again returns to step S1318, and repeats fec decoder.

When in the absence of crc error (S1324/ is no), or work as the execution of the fec decoder for determining up to the present to perform When number of times reaches predetermined maximum times (S1326 is no), in step S1328, CB connection units 2145 by one or more CB connects into CW.

In addition, in step S1330, the CW of the output connection of CB connection units 2145.This corresponds to the output in Figure 31 (B)。

Next, in step S1332, PHY layer controller 218 determine the need for by target CW feed back to multi-user/ Multilayer detector 212.Fix really in this case then will be described in detail referring to Figure 35.

When it is determined that (S1332/ is no) need not be fed back, the treatment terminates.

When it is determined that needing feedback (S1332/ is), in step S1334, soft bit buffer 2146 feeds back and target CB pairs The position LLR for answering.Specifically, soft bit buffer 2146 exports position LLR corresponding with target CB to de-rate matching unit 2147.

Then, in step S1336, de-rate matching unit 2147 performs rate-matched treatment to target position LLR feedbacks.

Then, in step S1338, CB connection units 2148 by the position LLR feedback links of one or more of CB into CW。

In addition, in step S1340, the CW that the output of CB connection units 2148 is obtained.This corresponds to the output in Figure 31 (C)。

Meanwhile, when determining also not perform multi-user/multilayer detection (S1302/ is no) to target CW in step S1302, In step S1342, PHY layer controller 218 determine target CW whether be initial transmission according to HARQ CW.

When it is determined that target CW is CW (S1342/ is) being originally sent, in step S1344, soft bit buffer 2146 will The position LLR of target CB is set to 0 and feeds back institute rheme LLR.Then, the treatment advances to step S1336.

On the other hand, when it is determined that target CW is CW (S1342/ is no) for resending, in step S1346, PHY layer control Device processed 218 determines whether to resend target CW using the HARQ with CC.

When it is determined that resending target CW (S1346/ is) using the HARQ with CC, in step S1348, soft bit is delayed Rush device 2146 feed back HARQ corresponding with target CB a preceding reception period preserve soft bit or position LLR.Then, the treatment Advance to step S1336.

On the other hand, when it is determined that not using the HARQ with CC to resend target CW (S1346/ is no), the before processing Proceed to step S1344.

Next, reference picture 35 to be described the determination treatment in step S1332.

As shown in Figure 35, first, in step S1402, PHY layer controller 218 determines target multi-user/multilayer detection Whether device 212 is using the treatment for repeating.

When it is determined that target multi-user/multilayer detector 212 does not use treatment (S1402/ is no) of repetition, in step In S1404, PHY layer controller 218 determines not needing the feedback of target CW.

When it is determined that target multi-user/multilayer detector 212 is using treatment (S1402/ is) for repeating, in step S1406 In, PHY layer controller 218 determines whether the number of times of the detection performed by target multi-user/multilayer detector 212 reaches and makes a reservation for most Big number of times.

When it is determined that the number of times of detection reaches the predetermined maximum times (S1406/ is), the treatment advances to step S1404。

On the other hand, when it is determined that the number of times of detection is not up to predetermined maximum times (S1406/ is no), in step In S1408, PHY layer controller 218 determines whether there is the crc error for target CW.

When it is determined that there is crc error (S1408/ is), in step S1410, PHY layer controller 218 determines to need mesh Mark the feedback of CW.

On the other hand, when it is determined that not existing crc error (S1408/ is no), in step S1412, determine that target is multiplex Whether family/multilayer detector 212 needs the feedback of another CW for detecting certain CW.

When it is determined that needing feedback (S1412/ is) of another CW, in step S1414, it is determined whether exist for except mesh The crc error of the CW outside mark CW.

When it is determined that during in the presence of crc error (S1414/ being) for the CW in addition to target CW, the treatment advances to step S1410。

On the other hand, when it is determined that not needing feedback (S1412/ is no) of another CW, or removed when determining not existing to be directed to During crc error (S1414/ is no) of the CW outside target CW, the treatment advances to step S1404.
